I feel like I have to post a reply to this (I am an extremely satisfied
3b2 user/programmer/administrator).

First, RTFM!  The System Administration Utilities Guide explains quite
clearly how to change the Firmware password -- just boot the `Floppy
Key'.  This will reset the firmware password to the default.

Second, RTFM!  Once again, the System Administration Utilites Guide
explains how to start an `Express Powerdown'.  If you "reached around
to power the beast off", you did NOT power it off, you simply started
`powerdown' running with all its defaults, specifically a 5 minute
grace period.  If you want to power the machine down as fast as
possible, log in as `powerdown', or try `shutdown -y -g0 -i0'.

I don't want to start a my-machine-is-better-than-yours war, but I
couldn't let this pass.  We currently have 3 3b2s (a 310 and 2 400s),
and are very satisfied.

Disclaimer: I am in no way associated with AT&T, I just like some of their
products.
